Another good day (Thursday, June 6) of work in the clean room around the disassembled AdSec-DX.
On the reference side
- Distribution boards. The back of the boards with contamination on the front did not show any problem. Boards were successfully cleaned (ultrasound bath). See before-after picture below.
- Actuators. Of the 40 actuators showing signs of rust, only one showed contamination on the actuator board and another one was found with a single spring contact.Both will be replaced.
- - Holes in the reference. For 15 of these 40 actuators, the hole in the reference showed some sign of contamination (white or black contaminant or oxidation).
On the shell side
- Attempts were made to remove the white contaminant on the back of the shell with alcohol, acetone and distilled water, to no avail, as seen on the before/after cleaning picture below.
- Preparation is made for the transport of the spare shell to the observatory.
